Model the physical, functional, and logical architecture of a system. Create visual representations with components, ports, and connections. Components represent architectural systems or subsystems to be used in system design. You can decompose components to add detail and define hierarchical relationships, and you can reuse and reference components across composition models. Create variant components and implement multiple design alternatives or variants, chosen based on programmatic rules.

Specify information exchange between components with interfaces. An interface defines the type, dimensions, units, and structure of the data contained within a port and exchanged between components. You can define interfaces locally that are saved with the model, or you can define interfaces in a System Composer™ interface data dictionary to be used across models.

Build an architecture model interactively through the user interface or programmatically using the command line.

Use projects to organize your work, manage files and settings, and interact with source control.
